get photo from iphone photo library and show in table view

I want to show all the images from the photo library in a table view. I am able to access all the images via assetsLibrary but unable to show them in table. I am not getting any kind of error but still don't know what is going on. ``` NSMutableArray *assets = [[NSMutableArray alloc]init]; ALAssetsLibrary *library = [[ALAssetsLibrary alloc]init]; [library enumerateGroupsWithTypes:ALAssetsGroupSavedPhotos usingBlock:^(ALAssetsGroup *group, BOOL *stop){ if(group != NULL){ [group enumerateAssetsUsingBlock:^(ALAsset *result, NSUInteger index, BOOL *stop){ if(result != NULL){ [assets addObject:result]; }else NSLog(@"NO photo");; }]; } } failureBlock:^(NSError *error){NSLog(@"Error");}]; ``` Datasource method for table view: ``` - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ NSString *identifier = @"id"; UITableViewCell *cell = (UITableViewCell*)[tableView dequeueReusableCellWithIdentifier:identifier]; if(cell == NULL){ cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier]; } [cell.imageView setImage:[UIImage imageWithCGImage:[[assets objectAtIndex:indexPath.row]thumbnail]]]; [cell textLabel].text = @"Photo"; return cell; ``` } Pleaes help what i am doing wrong.... thanks for help
